FUNCTIONS
Frozen
. The screen will freeze in the state it was in before the emergency mode became
active. The Emergency mode message will not be displayed, thus, showing no sign to the
observer that the emergency mode has been triggered.
Blank
. The screen will blank giving no indication to others that the radio is in emergency
mode.
When emergency mode is triggered, the radio can be configured by the FPP to transmit and
receive on a cyclic basis with FPP programmed time periods.
During Tx, the radio will generate an emergency broadcast call on either the currently selected
channel or an FPP nominated channel.
Others may listen to the automatic transmissions to hear conversations near the radio.
Turning the radio off and on will disable emergency mode.

UNCTIONS
The Scan Function allows the sequential searching of up to 16 channels, if the selected zone
channel is programmed as a Scan channel, for a valid signal (Carrier + CTCSS/DCS tone for
Analogue FM or Colour Code for DMR). When found, the radio will stop on that channel until the
signal disappears again.
If scanning is enabled on your radio, press the
F4
button from the Main Channel Screen to enter
Scan Mode, or select a channel that has been programmed as a scan channel. Once selected, the
scanning will either start automatically, if programmed, or the programmed scan function button will
need to be pressed. (FPP configurable).
While listening on the channel, the user is able to PTT on that channel. After the signal
disappears, the radio will remain listening on the channel for a short time (FPP configurable,
typically 3 seconds) before resuming scanning.
If a Priority Channel is assigned to Scan mode, the radio will interleave a check of this channel
between each normal Scan channel. The radio may also check the Priority Channel every few
seconds while stopped on a channel. If a signal is found on the Priority Channel then the radio will
switch to that channel immediately.
